BR-CO-09: VAT identifier prefix error
Seller, buyer and tax-representative VAT identifiers must begin with an ISO 3166-1 alpha-2 country prefix; Greece may use EL.
Where to look in UBL
//cac:PartyTaxScheme[cac:TaxScheme/cbc:ID='VAT']/cbc:CompanyID
How to investigate the error
Inspect each VAT CompanyID and verify that its first two characters are the permitted country prefix for the identifier.
Can RejectFix repair this automatically?
RejectFix can report implemented checks and only offers a deterministic repair when the intended value is unambiguous. Business identifiers, dates, payment terms and accounting values must come from your source system rather than being invented.
Scope: This guide explains the official rule, but RejectFix is not the official OpenPeppol Schematron or an Access Point and cannot guarantee acceptance. Confirm the current requirement with your Access Point.
